Hi,
I'm migrating Java 1.7 to 1.8 and JbossEAP6.1 to WildFly14.0.1.
we are on AWS and we notice on the logs of the dockers that there are many errors of the type:

[GC (Allocation Failure)  1085489K->562034K(1908224K), 0.0661752 secs 
and when we do performance tests, sometimes dockers crashs.
we already analysed the heap dump and we didnt notice any thing special in our application code.

i'm using this configruation to start my WildFly Server : 
JAVA_OPTS -Xms1920m -Xmx1920m -XX:MetaspaceSize=480m -XX:MaxMetaspaceSize=960m -XX:MaxPermSize=1920m -XX:+UseParallelGC -verbose:gc

can any one please help me on this subject.
Thanks
